Here are some of the benefits of pharmacogenomics
Pharmacogenomics
Pharmacogenomics (a portmanteau of pharmacology and genomics) is the study of the role of genetics in drug response. It deals with the influence of acquired and inherited genetic variation on drug response in patients by correlating gene expression or single-nucleotide polymorphisms with drug absorption, distribution, metabolism and elimination, as well as drug receptor target effects.

Its long-term goal is to help doctors select the drugs and doses best suited for each person. It is part of the field of precision medicine, which aims to treat each patient individually. Your genes determine a lot about how you look. They also play a key role in how medications work in your body. Credit: NIH.
Can doctors prescribe drugs to people who don't have genes?
In addition, if scientists can identify genes that cause serious side effects, doctors could prescribe those drugs only to people who do not have those genes. This would allow some individuals to receive potentially lifesaving medicines that otherwise might be banned because they pose a risk for other people.
Can different people have different versions of the same gene?
Different people can have different versions of the same gene. Each version has a slightly different DNA sequence. Some of these variants are common, and some are rare. And some affect health, such as those gene variants linked to certain diseases. Scientists know that certain proteins affect how drugs work.
